-## About Commitizen
+### About Commitizen
 
 Commitizen is an open source project that helps contributors be good open source citizens. It accomplishes this by prompting them to follow commit message conventions at commit time. It also empowers project maintainers to create or use predefined commit message conventions in their repos to better communicate their expectations to potential contributors.
 
-## Commitizen or Commit Hooks
+### Commitizen or Commit Hooks
 
 Both! Commitizen is not meant to be a replacement for git commit hooks. Rather, it is meant to work side-by-side with them to ensure a consistent and positive experience for your contributors. Commitizen treats the commit command as a declarative action. The contributor is declaring that they wish to contribute to your project. It is up to you as the maintainer to define what rules they should be following.
